Earlier this month, Recode reported that Nest had explored its own Echo-like product. But Nest ultimately abandoned the plans, partly out of concerns that an always-listening virtual assistant with ties to Google might freak people out. The Information now reports that Nest wanted to be involved with Google’s connected-speaker efforts, but was rebuffed.

Where does that leave Nest? The company may now be turning its attention to home security, with three projects in development. One project, called “Keshi,” would automatically lock doors when everyone’s left the house, tying into the Home-Away detection in Nest’s existing thermostat, smoke detector, and security cameras. Another project, called “Pinna,” would detect when doors are open or closed, and would connect to the Internet via a third device called “Flintstone.” (These are probably all code-names.)

It’s unclear, however, when any of these products might launch. The Information, which revealed the product details as part of a larger story on Nest’s struggles, claims that Nest has revised or killed some of its security efforts several times.

Why this matters: Day by day, it seems like Alphabet is turning Nest and Google’s smart home efforts into one of the company’s notorious A/B tests. While Nest has built up some clever integrations with other smart home products, it hasn’t added any of its own new product types since acquiring Dropcam in 2014. And while Google is getting into smart home hardware with products like OnHub, its own Brillo operating system and Weave API for smart homes is still in its infancy. With so many Internet of Things platforms kicking around, at some point it won’t make sense for Alphabet to have two completely different approaches happening under the same roof.
